{SOLVED] Trouble getting a child ID

I’m able to generate the correct child in an array using either my php or Brunos’s. I am just unable to figure out how to get the data from that array to format as a number rather than the string "Array ( [62] => 62 ) 1"

Sort of losing my mind over this. It’s right there, but I’m too dumb to figure it out. LOL

Here’s something I’ve used before :

<?php
$pid = $modx->documentIdentifier;
$allChildren = $modx->getAllChildren($id= $pid, $sort= 'menuindex', $dir= 'ASC', $fields= 'id');
$firstChild =  $allChildren[0]['id'];
return $firstChild ;
?>

It will return the id of the first child document.

I created a snippet called firstChildId with the exact content bunk58 posted above yet when I call it with [[DittoFormat? &parents=`[[firstChildId]]` &display=`all` &tplItem=`modellItem` &group=`4` &sortBy=`menuindex` &sortDir=`ASC` &tplGroup=`modellGroup` ]] it gives me a parse error:

« MODx Parse Error »MODx encountered the following error while attempting to parse the requested resource:

What am I doing wrong?

Try alternating the caching of the snippet calls :

[!DittoFormat? &parents=`[[firstChildId]]` &display=`all` &tplItem=`modellItem` &group=`4` &sortBy=`menuindex` &sortDir=`ASC` &tplGroup=`modellGroup`!]
